SUMMARY:Light as a Mechanism to Tailor Diffusion
DESCRIPTION:Featuring Manuel I. Marques\, Universidad Autonoma de Madrid\,S
	pain.\nHosted by: H. Eugene Stanley\n\nPart of the Biophysics/Condensed Mat
	ter Seminar Series.\n\nABSTRACT\n\nOptical trapping\, driving and shorting 
	of small objects has become a\ntopic of increasing interest in multidiscipl
	inary sciences. In this talk\nwe show how the diffusion of small metallic n
	anoparticles in a liquid\ncan be tailored by illuminating the system with a
	 stationary\nelectromagnetic field. By changing the phase of the radiation 
	we can\ndecrease or increase the diffusion constant bellow and above the\ns
	tandard Brownian value [1\,2].\n\nWe also show how a chain made of these me
	tallic nanoparticles can be\nused as a resonant light sail\, attached by on
	e end point to a\ntransparent object and propelling it by the use of electr
	omagnetic\nradiation [3]. Interestingly\, there is a window in the frequenc
	y\nspectrum of the radiation in which a null torque equilibrium\nconfigurat
	ion\, with a minimum geometric cross section\, corresponds to a\nmaximum in
	 the driving force.\n\n[1] S.Albaladejo\,M.I.Marques\,F.Sheffold\,J.J.Saenz
